Number Representation

← Back to Domain-Specific Abstractions by Domain

4 domain-specific abstractions whose origin domain is Number Representation.

• Complex-base system — Represent real or complex numbers positionally using a nonreal radix and a finite digit alphabet, allowing a single unsigned expansion to encode multiple dimensions when admissibility, convergence, and uniqueness conditions hold.
• Decimal representation — A positional base-ten digit expansion of a nonnegative real number, with finite integer part and finite or infinite fractional part.
• Engel expansion — A representation of a positive real number as a sum of reciprocals of cumulative products from a unique nondecreasing integer sequence.
• Non-integer base of numeration — Represent numbers positionally with a real or complex radix that is not an integer, making admissible digits, expansion algorithms, and nonuniqueness depend on the radix.
